The Doppstadt SM 518 rotary screener is a popular machine for screening and sorting materials. This used, unreconditioned model offers robust features and reliable performance. Here's a detailed spec sheet describing the screener as a used machine and including all the necessary details.

The Doppstadt SM 518 rotary screen is designed to screen large quantities of solid materials. With a 4,700 mm long and 1,800 mm diameter drum, it is suitable for applications requiring effective separation of materials of different sizes.

Make and Model : Doppstadt SM 518.

• Make and Model : The rotary screen used is a Doppstadt SM 518. This model is built to last and withstand harsh working conditions.

• Main Components:

  • Rotating Drum : The heart of the machine, measuring 4,700 mm in length and 1,800 mm in diameter. It is designed to withstand wear and heavy loads.
  • Engine : Mercedes Benz engine with a power of 41 kW (60 hp), designed to ensure efficient and constant rotation of the drum.
  • Support Frame : Sturdy structure that supports the drum and allows it to rotate.
  • Feeding System : Introduces materials into the drum for screening.
  • Discharge System : Expels the separated materials after screening.

• Measurements and Features:

  • Drum Length : 4,700 mm
  • Drum Diameter : 1,800 mm
  • Drum Perforation : Variable from 10mm to 80mm, allowing for precise adjustment of particle size.
  • Drum Thickness : Varies from 6mm to 12mm, affecting the strength and capacity of the drum.
  • Weight : 13,000 kg

• Installation:

  1. Placement : Place the rotary sieve on a flat, stable surface.
  2. Connection : Make sure the motor and power system are properly connected.
  3. Alignment : Make sure the drum is aligned correctly to avoid vibration and excessive wear.

• Normal Operations:

  1. Start : Turn on the engine to start the drum rotation.
  2. Material Loading : Introduces the materials to be screened through the feeding system.
  3. Screening : The materials are passed through the drum, which separates the particles based on the size of the holes in the screens.
  4. Discharge : The screened and separated materials are expelled through the discharge system.

• Interchangeable Nets : Different nets to adapt the size of the holes according to the screening needs.
• Conveyor Belts : To facilitate the transport of materials before and after screening.
• Control Systems : To monitor and regulate rotation speed and material flow.
• Cyclones and Separators : For further separation and filtering of materials.

• Rotation Speed ​​(N):

  $$N$$

  where RPMRPM $RPM$ is the rotational speed of the drum and DD $D$ is the diameter of the drum.

• Screen Flow Rate (Q):

  $$Q$$

  The volume per cycle depends on the length and diameter of the drum.

The Doppstadt SM 518 rotary screen can work with:

• Earth and Sandblasting
• Building Materials
• Compost and Organic Waste
• Industrial Waste

It is not suitable for excessively wet or oversized materials without adequate pre-treatment systems.

• Periodic Inspection : Inspect the drum and support frame for signs of wear and damage.
• Lubrication : Make sure the motor and drum bearings are adequately lubricated.
• Cleaning : Remove debris and accumulated materials from the drum and surrounding areas.
• Inspection : Check mechanical parts regularly and replace worn or damaged ones.

• External Conditions : Check the condition of the drum and support frame for signs of wear or damage.
• Operation : Test the machine to ensure that there is no abnormal vibration and noise during operation.
• History of Use : Ask about past use and maintenance to assess durability and reliability.

The Doppstadt SM 518 rotary screen is used in:

• Mining Sector : Separation of minerals and aggregates.
• Waste Management : Solid waste screening and composting.
• Construction and Demolition : Classification of construction and demolition materials.

Buying a used rotary screen offers numerous advantages:

• Lower Cost : Significantly lower price than a new one.
• Immediate Availability : Ready to use without long lead times for production.
• Sustainability : Contributes to environmental sustainability by reducing the need for new materials and resources.

The used, unreconditioned Doppstadt SM 518 rotary screen, with its robust dimensions and features, is an excellent choice for applications requiring effective material separation. If you have any other questions or need more details, I'm here to help!
